To aZZ whom it may concern.-

Beit known that we, ADONIEAM J. PALMER and GEORGE H. PALMER, both of Brooklyn, in the county of Kingsand State of New York, physicians, have invented a certain new and useful Improvement in Atomizers and In- ?alers, of (which the following is a specifica- D.

We will'describe our. apparatus as applied, for atomizing liquid by compressed air received from areservoir, as more fully set forth in at: previous patent to us,.dated July 5, 1887,; No. 366,022. We have discovered that are,

effect is improved by surrounding the nozzle from which the compressed air is discharged chamber, which is perforated to admit the liquid slowly.

The success of the atomizing operation is affected by variations in the level ofthe liquid. When the surface of the liquid is too high and the nozzle is 'too deeply immersed, the escape of air isretarded, and the efficiency of the atomizing is reduced. When,

on the other hand, the levelof the liquid sinks .45

too low, so that the nozzle is completely uncovered, the atomizing stops. We have in our patentof 1887, referred to, provided for tilting the vessel, so as to allow the immersion of the nozzle to the right depth with varying quantities of liquid in the vessel. Our present invention avoids the necessity of such adj ustthe nozzle.

The level of the liquid takes care of So-long as there is sufficient liquid in the vessel it will flow through the limited- ,'in quantity of the liquid will induce .only a slight increase in the rapidity with which the liquid will flow inward and be presented to The chamber will restrain the excess with such approximate uniformity that the atomizing will proceed successfully with a wide range in the height of the liquid.

Our apparatus will serve for atomizing the various'liquids required in this condition for medicinal uses. It will also serve under proper cleaning.

Similar letters of reference indicate corresponding parts in all the figures where they occur.

A is a foundation of wood, B a globe or vessel of glass fixed thereon, and B a nozzle, which receives a plug, 0, of soft vulcanized rubber or other suitable material, perforated to receive the pipes.

D is an air-induction pipe, of glass,receiviug -the air through a flexible hose, E, and discharging-it at a high pressure through a fine perforation in the upturned nozzle D. The conditions are favorable for atomizing the liquid provided the liquid be preventedfrom flowing too deeply over the orifice. The exterior of the nozzle D is formed with screwthreads d.

G is an open-topped easing or chamber which performs important functions. Its lower I end has a hole which is tapped or otherwisetreated to produce screw-threads 9', matching on the screw-threads d. This chamber G is of glass. In the process of forming it two or more thin projections are forced outward near the bottom, and by removingthe material at the apex of one or more of these projections orifices g are provided, which admit the water or other liquid nearly or quite as fast as the jet of air issninfrom D can atomize it. These orillces can to conveniently enlarged at any time by delic: .ely filing the apexes of the projcctions.

His a pipe inserted through the plug 0, and having a turned-up outer end secured by a cork, It. The t5 mid to be atomized is supplied from timer time through this pipe.

1 is a pipe, of lass or other material in sorted through the plug G, and connecting by the flexible hose, made in two lengths, J J", with a tip, K, which, when the apparatus is used for medical purposes, is held in the mouth of the patient, who inhales through this pipe I and exhale-s through the nostrils; or, it'prelerred, the exhalation may be through this same mouthpiece K, provided with a branch yalve attachment. (Not shown.)

ill is an annular trap having on its upper edge a eapacious nozzle, which, on removing the cork or, gives facilities for thoroughly washing the interior.

M M? are nozzles at the center, by which the two lengths of rubber hose J J are conveniently attached.

in the use of our apparatus the liquid,whicl 1 may be supposed to be water or oil, either pure or variously medicated, may be introduced through the pipe H without much nicety in regard to rpn'niitity. It is sufficient that it till the base of the globe 13 above the orifice g and not above the top ofthe chamber G. Then, inserting the tip K in the mouth of the patient, the cock L is opened cautiously and a sufficicnt blast is allowed to flow from the reservoir L of compressed air through the hose E and piped), issuing upward through the nozzle D, and rapidly throwing out any excess of liquid which had previously been received in the chamber (l. New, tin; blast of air con tinning, atomizing will. t'eonanence, and the liquid, slowlv enteringthrough the limited apertures y will be atomized and mingled with the air, hlling the upper portion of the globe The patient, Inhaling't'rom the mid height in the globe l3, tindsthe air well filled with the llqnid in the iamlliar atomized condition. Any excess of liquid thrown upward from the chamber at the commencement of the operation, or at any later period, will strike the top of the interior of the globe and adhere, trickling down the sides to again mingle with the liquid in the bottom. Any excess of liquid which shall chance to be drawn out through the pipe I and the lirst length of hose, J, will hill by gravity into the lower portion of the trap M. Any saliva from the mouth of the patient descending through the second length of hose, J, will be similarly stopped.

Alter each use of the apparatus,the plug or is removed and the trap thoroughly washed by injecting through the orilicc or by other obvious means.

An important Function in the treatment of some liquids is performed by the chamber (l in arresting the disturbing influence due to foaming and to lllPglllill motions of the mass of liquid lying in the vessel B. The chamber G not only prevents the disturbance oi the action by variations in the level of the llql1 l(i but also prevents disturbance by agitation" and foaming of the liquid. S0 soon as tho operation has fairly commenced the strong blast of air rising from the nozzle D findsajust sufficient depth of tranquil fluid withinthe chamber G to allow its most favorable action.

Although no have used the term fatomizer, it will e no ood that in ordinary practice, blmviu; val quantities of warm dry air ready to absorb the vapor, the liquid is in the course of the treatment evaporated, and its vapor mingles with the air and is con; w veyed to the iungs through the inhaling-tube; in the form mainly of vapor. The terms atomizer and vaporizer may be used in this relation as ct' uimlents.

Modifications may be made in, the-details without departing from the principle orsacrificing the advantages of the invention.

\Ve can vary the form of the nozzle D within wide limits so long as it isadapted to project the air upward in one or more small and strong streams. The foundation-piece A may be of glass, cast or otherwise formed in tegral with the globe B. The chamber G, with its screw-threaded apertures to match on the nozzle, and with its fine aperture or apertures 5 may be made of other material than glass. W'c propose to use hard rubber in many cases.

The supply of liquid may be introduced through a branch of the inhaling-pipe I, havinga proper plug, and thus the special filling- 05 pipe H and its plug it may be dispensed with.v We prefer the whole as shown.

Ne claim as our invention '1. The open-topped chamber G, wit-h one or more apertures for the slow admission of the rro liquid, in combination with the globe or vessel B, air-induction pipe D, with its contracted aperture D, and inhalingpipe Larranged and adapted to serve substantially as herein t-tI'lCCh fied.
